The AssemblyInfo file of add-ins created with the add-in wizard has the following attribute:

<Assembly: ComVisible(True)> 

Since add-ins for VS 2010 are managed add-ins that are not registered for COM Interop, one would think that the attribute could be changed to:

<Assembly: ComVisible(False)> 

But doing this causes error 80004002 (No such interface supported) when trying to load the add-in.
